Power connections, minimum and maximum wiring capabilities, tightening torque

1 Wiring - power terminals Power Observe the cable cross-sectional areas recommended in the standards. The soft starter must be grounded to conform to the regulations concerning leakage currents. If the installation involves several soft starters on the same line, each soft starter must be grounded separately. Keep the power cables separate from circuits in the installation with low-level signals (sensors, PLCs, measuring devices, video, telephone).

6 Wiring - control terminals Types of command LI1 stop behavior LI1 assignment is stop and cannot be changed by HMI or serial link. This input is active on level (Low level (0) = stop). RUN and START management RUN and START can only be assigned to LI2 (not LI3). In 2-wire control On power-up or on manual trip reset, the motor will restart if the RUN command is present. Control supply LI2 Motor In 3-wire control On power-up or a manual trip reset or after a stop command, or a change of assignment, the motor can only be powered once the START input has been opened (state 0) followed by a new pulse (state 1). When switching from remote command to local command, with Run order present on the terminal control, the motor doesn t start in 3-wire control: need to remove Run order and apply it again.
